Fireplace repair in Kennesaw typically runs $250 – $850 depending on what’s wrong, with gas fireplace service usually landing between $195 and $400. Most repairs we handle in Kennesaw are completed same-week, not same-day, because we show you camera footage before we recommend anything. That matters here more than most places.

Why Ashby Chimney Marietta Is Kennesaw’s Preferred Fireplace Repair Company
Nathan Corliss leads Ashby Chimney Marietta, and the standard his crews follow in Kennesaw is simple: say the price, show up in the arrival window, leave it cleaner than you found it, put the guarantee in writing, and come back if it fails. That’s the Kingswell Way, and it’s why homeowners who’ve been burned by no-shows and price-switching contractors call us. We’ve been at this since 2002, and our technicians are background-checked and uniformed, so you know exactly who’s walking into your home.
Where local knowledge really pays off is with Kennesaw’s housing stock. The historic districts east of Kennesaw Mountain have brick chimneys running 80 to 120 years old, often with unlined flues. The subdivisions off Stilesboro Road and Jiles Road trend toward zero-clearance and factory-built units from the 1990s and 2000s. We know which failure patterns to look for in each. Our Fireplace Repair team carries parts for both, and we’re honest when a repair can wait.
The thing Kennesaw homeowners tell us they value most is this: no recommendation without camera evidence. If you have a cracked firebox in a home near Swift-Cantrell Park, you’re going to see the crack on our screen before we ask for a dollar. If a liner is spalling in a 1920s bungalow off Cherokee Street, you’ll watch that footage too. That standard has built our local reputation, and it’s why people from Acworth to Woodstock refer us.
Styles & brands we work with





Gas Fireplace Repair in Kennesaw
Gas fireplace repair in Kennesaw usually runs $250 – $600, and the most common calls we get are for pilot lights that refuse to stay lit, thermocouples or thermopiles that have worn out, and gas valves that were never adjusted properly after installation. In Kennesaw specifically, homes built in the 1980s through 2000s subdivisions like Legacy Park and Barrett Greene often have original gas fireplaces that have gone 15 – 25 years without a service call.
Pilot Light and Ignition Repairs
A pilot light that won’t hold, or that fires and then drops out seconds later, usually points to a failing thermocouple, a dirty pilot assembly, or a gas pressure issue. We test each in sequence and replace only what’s actually failed. You’ll know the price before we touch anything.
Valve and Burner Repairs
When a burner lights unevenly or not at all, the valve, burner ports, or gas supply line are the usual suspects. We use OEM-compatible parts from Famco and Copperfield rather than whatever generic piece happens to be on the truck. The difference shows up two winters later when it still fires on the first click.
Gas Fireplace Service in Kennesaw
Gas fireplace service in Kennesaw costs $195 – $400, and it’s the kind of maintenance our crews recommend annually, even for fireplaces that get used only a handful of times each winter. The mild winters in Kennesaw create a specific risk profile: because fireplaces sit idle for eight or nine months, dust, spider webs, and oxidation accumulate inside the burner and pilot assembly. When you finally fire it up in December, those contaminants can cause delayed ignition, sooting, or a tripped safety sensor.
Full System Inspection and Cleaning
A proper gas service includes removing and cleaning the logs, clearing the burner ports, checking the pilot assembly, testing the safety sensors, and verifying gas pressure at the valve. We also inspect the venting, because blocked or disconnected venting on a gas fireplace is a carbon monoxide risk, plain and simple.
Safety Sensor Testing
Kennesaw homes with factory-built gas units often have original sensors that have degraded from humidity. We test oxygen depletion sensors and thermocouples under load, not just at rest. If a sensor has drifted out of spec, we’ll show you the reading and quote the replacement before doing it.
Trusted Brands We Service in Kennesaw
We repair and service gas fireplaces, wood-burning units, and inserts from manufacturers including HeatShield, DuraFlex, and Famco, and we keep common replacement parts stocked for the brands most widespread in Kennesaw’s housing stock. That means faster turnaround for homeowners around Kennesaw Mountain and the subdivisions off Old 41 Highway, because we’re not waiting on a supplier shipment for a thermocouple or a pilot assembly. When we do need a specialty part, which happens with older inserts and original 1990s gas valves, we’ll tell you the expected lead time and the exact cost before ordering.

AfterCommon Fireplace Repair Problems We See in Kennesaw Homes
- Cracked clay flue liners in pre-WWII homes. Kennesaw’s oldest brick chimneys, especially those near the downtown historic district, often have clay tile liners that have spalled from humid summers and winter freeze-thaw cycles. These cracks let heat and gases reach combustible framing around the flue.
- Rusted chimney caps and deteriorated crowns. The humid subtropical climate means rain and humidity sit on exposed masonry for months. Water soaks into the firebox, causing efflorescence, spalling brick, and rusted dampers that freeze open or shut.
- Acidic condensate eating mortar joints. Older homes that vent gas appliances through masonry chimneys without proper liners develop acidic condensation that corrodes mortar from the inside out. This usually surfaces during a Level 2 inspection after someone notices a draft or a smell.
- Neglected gas fireplaces in 1990s – 2000s subdivisions. Homes around Legacy Park, Barrett Greene, and the subdivisions near Due West Road often have zero-clearance fireplaces that have never been serviced. Dust, oxidation, and degraded sensors lead to delayed ignition or a fireplace that won’t light when the first cold snap hits.

FAQs About Fireplace Repair in Kennesaw
Because homes built before World War II in Kennesaw’s historic districts often have chimneys with clay-tile liners, or no liner at all, and those materials crack and spall after 80 – 120 years of Georgia humidity and freeze-thaw cycles. Newer subdivisions from the 1980s onward use factory-built chimneys with stainless steel liners that don’t deteriorate the same way. The fix for older chimneys is usually resurfacing with HeatShield or installing a DuraFlex liner, not rebuilding the whole stack. If you want to know what condition your flue is actually in, call (478) 796-8742 and we’ll put a camera up it before recommending anything.
Kennesaw’s humid subtropical climate means two things for fireplaces: rust and spalling. Chimney caps rust out faster here than in drier climates, letting water into the flue and firebox. That water soaks into mortar joints and brick, then freezes on the occasional winter night below 32°F, popping small pieces of masonry loose. The pattern is visible as white efflorescence on the firebox walls or crumbling mortar in the flue. We address it by replacing caps and crowns, repointing damaged mortar, and sealing only when appropriate, which is not every chimney.
Yes, and this is one of the most common repairs we do in Kennesaw’s older homes. A gas appliance vented through an unlined or clay-tile chimney produces acidic condensate that eats mortar joints and eventually compromises the flue. The repair typically involves installing a correctly sized stainless steel liner from DuraFlex or resurfacing the flue with HeatShield to isolate the gases and protect the masonry. We’ll show you camera footage of the damage before quoting, and every liner install carries the written Kingswell Guarantee.
Yes, sometimes more so. A fireplace that sits unused for most of the year in Kennesaw accumulates dust, rust, and debris, and moisture keeps working on the masonry year-round, even when there’s no fire. By the time you light the first fire in January, the damper may be rusted, the pilot may be fouled, and the chimney cap may have leaked all autumn. A repair done now costs less than a larger repair done after the damage compounds. If you’re unsure, we’ll do a camera inspection and tell you straight whether it can wait.
In subdivisions built during that era, the most common repair by far is gas fireplace service and pilot light repair. These homes have zero-clearance, factory-built fireplaces with gas logs that have been used for 15 – 25 years without maintenance. We replace worn thermocouples, clean fouled burners, and correct gas valve settings. The second most common is chimney cap replacement, because those original caps have rusted through in the humidity. For a free estimate, call (478) 796-8742 and we’ll get you on the schedule.
In Kennesaw specifically, the historic districts near Kennesaw Mountain present a repair profile you won’t find in neighboring suburbs. Many original brick chimneys from the 1890s through 1930s lack modern flue liners entirely. Some have clay-tile liners that are now cracked and spalling from decades of humidity and freeze-thaw cycles, conditions that simply don’t exist in homes built after 1980 in the subdivisions off Stilesboro Road. When we inspect those older chimneys, we regularly find deteriorated mortar joints and unlined stacks venting gas appliances, which means acidic condensate has been eating the mortar for years. Last winter, our crew repaired a fireplace in a 1920s home near downtown Kennesaw where the clay flue liner had cracked and the damper was rusted open. We installed a HeatShield resurfacing system after showing the homeowner camera footage of spalling mortar and second-degree creosote, restoring a safe draft without rebuilding the entire chimney. That’s the kind of repair you can’t quote blind, and we never do.
Our standard on every Kennesaw job is what it’s always been under Nathan Corliss: no camera recommendation, no written-price repair. We don’t tell you a liner is shot because it’s the expensive fix. We show you the footage, say what it costs, and let you decide. Call (478) 796-8742 and a live person will answer, day or night.
